[HTML][HTML] Progress in the theory of singular Riemannian foliations

MM Alexandrino, R Briquet, D Töben - Differential Geometry and its …, 2013 - Elsevier
A singular foliation is called a singular Riemannian foliation (SRF) if every geodesic that is
perpendicular to one leaf is perpendicular to every leaf it meets. A typical example is the …

Polar manifolds and actions

K Grove, W Ziller - Journal of Fixed Point Theory and Applications, 2012 - Springer
A group action is called polar if there exists an immersed submanifold (a section) which
intersects all orbits orthogonally. We show how to construct a manifold admitting a polar …

A filtration for isoparametric hypersurfaces in Riemannian manifolds

J Ge, Z Tang, W Yan - Journal of the Mathematical Society of Japan, 2015 - jstage.jst.go.jp
This paper introduces the notion of k-isoparametric hypersurface in an (n+ 1)-dimensional
Riemannian manifold for k= 0, 1,..., n. Many fundamental and interesting results (towards the …

From isoparametric submanifolds to polar foliations

G Thorbergsson - São Paulo Journal of Mathematical Sciences, 2022 - Springer
We will show how isoparametric submanifolds and polar actions on round spheres lead to
polar foliations and polar actions on compact symmetric spaces and compact Riemannian …

On isoparametric foliations of complex and quaternionic projective spaces

M Dominguez-Vazquez, A Kollross - arXiv preprint arXiv:2409.06032, 2024 - arxiv.org
We conclude the classification of isoparametric (or equivalently, polar) foliations of complex
and quaternionic projective spaces. This is done by investigating the projections of certain …

Collapse of the mean curvature flow for equifocal submanifolds

N Koike - 2011 - projecteuclid.org
In this paper, we investigate the mean curvature flows having an equifocal submanifold in a
symmetric space of compact type and its focal submanifolds as initial data. It is known that …

[HTML][HTML] Austere and arid properties for PF submanifolds in Hilbert spaces

M Morimoto - Differential Geometry and its Applications, 2020 - Elsevier
Austere submanifolds and arid submanifolds constitute respectively two different classes of
minimal submanifolds in finite dimensional Riemannian manifolds. In this paper we …

[PDF][PDF] An introduction to isoparametric foliations

M Domínguez-Vázquez - Preprint, 2018 - verso.mat.uam.es
A hypersurface in a Riemannian manifold is called isoparametric if it and its nearby
equidistant hypersurfaces have constant mean curvature. These geometric objects, as well …

Curvatures and austere property of orbits of path group actions induced by Hermann actions

M Morimoto - Transformation Groups, 2022 - Springer
It is known that an isometric action of a Lie group on a compact symmetric space gives rise
to a proper Fredholm action of a path group on a path space via the gauge transformations …
